After obtaining a rebuild kit, inspect and test fit all bushing drivers. Those that are too loose may suffer damage during installation, and those that are too tight may seize. Inspect all small parts springs and other hardware, but do not remove these items from the bag until needed. Study the instructions, and refer to any relevant repair manuals in order to become familiar with the rebuilding process prior to beginning any work.

After unmounting the transmission and disassembling the catch pan, linkage and valve body, place the transmission on a suitable work surface. It may be helpful to have a clean table nearby to lay out, organize and clean smaller parts. Clean all parts one at a time, and replace the clutch plates and any internal components that appear worn. Complete the process by reassembling the transmission before reattaching it to the vehicle.
